Question

Which material has highest dielectric constant?

Answer 1

1. Titanate of calcium and copper has the highest dielectric constant.
2. The proportion of a substance's permittivity to the permittivity of free space is known as the dielectric constant.
3. It is mathematically expressed as: $\begin{array}{l}\kappa =\frac{\epsilon }{{\epsilon }_0}\end{array}$ ,
4. Where, $\kappa$ is the dielectric constant, $𝜺$ is the permittivity of the substance, ${𝜺}_0$ is the permittivity of the free space.
